WILLIAM TAYLOR, OF MAYNARD, MASSACHUSETTS, ASSIGNOR OF ONE-HALF HISRIGHT TO WILLIAM MAYNARD, OF SAME PLACE.

IMPROVEMENT IN' PICKERS FOR LOOMS.

Specification forming part of Letters Patent No. 135,253, dated January28, 1873.

To all whom it may concern:

Be it known that I, WILLIAM TAYLOR, of Maynard, in the county ofMiddlesex and State of Massachusetts, have invented certain Improvementsin Pickers for Looms, of which the following is a specification:

In the drawing, Figure 1 shows, in perspective, one common form ofpicker, broken by use as they generally break, and the object of myinvention is to strengthen pickers at this point; and my inventionconsists in a picker made in the ordinary way, except that a sheet ofmetal is incorporatedwith it to give it greaterstrength.

Fig. 2 is a plan of my improved picker composed of rawhide securedtogether with rivets, and made in all respects in the usual way that is,like Fig. 1-except that a sheet of metal is formed, as shown in thedrawing, so as to extend from the plug down into the shank of thepicker.

In all the figures a a represent the'metal.

Fig. 3 shows a modification of my invention, designed principally to beused in repairing pickers which have been thrown aside.

The upper part A (see Fig. 1) of the wornout picker is out off and asheet of metal, a, inserted in the shank of the picker and bent properlyto receive the plug B. A sheet ofrawhide is also inserted in the shank,and over this metal sheet a, and a second sheet of metal, a, over thisrawhide sheet, the whole being secured to the shank and spindle hole (3and D by rivets in the usual way, as will be plain to all skilled in theart from the drawing. These metal sheets I usually make of about thesame width and shape as the rawhide sheets, only a little narrower toprevent them from projecting so as to be struck by the'picker-stiok.

In some cases, where the neck or shank is made very strong, thespindle-hole D gives out; and Figs. 4. and 5 show the application of myinvention to strengthening the connection between the shank and thesleeve D, which will be plain without further description.

I have shown my invention as applied to one form only, but it is equallyapplicable, of course, to any other form of picker.

I find that pickers strengthened with metal, as above described, willlast over four months, while pickers such as shown in Fig. l rarely lastas much as two weeks; and my improved picker operates precisely as wellin every respect, and costs very little more. I use Russia sheet-iron,but sheet-steel or other tough metal sheets or strips will answer.

1 am aware that the use of a metal hoop around the plug is not new, andtherefore I disclaim'the use of metal generally in connection withrawhide pickers.

What I claim as my invention is 1. A rawhide picker having its plugconnected to its shank, as above described.

2. Arawhide picker having its spindle-sleeve connected to its shank, asabove described.

WILLIAM TAYLOR.
